Abstract (en)

[origin: WO9951906A1] A pipe joint for connecting a plain pipe end (2). The joint has a bell which has a socket (1) defined therein. The socket (1) includes an axis, a conical surface (1a), a first cylindrical surface (1d) of smaller diameter extending from one end of the conical surface (1a), a bottom (1c) of the socket (1) adjacent the first cylindrical surface (1d) for seating the pipe end (2), and a second cylindrical surface (1e) of larger diameter extending from the other end of the conical surface. A gasket (4) is disposed adjacent the conical surface (1a) prior to sealing with the conical surface (1a) acting as a gasket seat during sealing of the gasket. A gland (3) is provided and has a radially extending handle (9) for rotating the gland (3) from outside the bell. A breech lock mechanism is provided which includes internal segments (1b) on the second cylindrical surface (1e) of the socket (1) and corresponding, cooperating external segments on the gland (3), the internal and external segments having matching, mirrored inclined plane surfaces for engagement with each other.
